ISRO’s Reusable Launch Vehicle :-

The first technology demonstrator (TD) launch of the Indian Space Research Organisation’s Reusable Launch Vehicle (RLV), or the spaceplane in popular parlance, will take place soon from the Satish Dhawan Space Centre (SDSC), Sriharikota,

However, the popular perception of the technology as a marriage between rocket and aircraft is a misnomer.

The objective is to achieve hypersonic speeds to basically test the hypersonic aero-thermodynamic characterisation of the winged body’s re-entry, its control and guidance systems, autonomous mission management to land at a specific location at sea and testing of “hot structures” that make up the structure of the RLV.

Complex technology

A conventional launch vehicle (LV) spends the lowest time of its flight in the atmosphere, whereas the RLV system spends all the time in the atmosphere. Also, while an aircraft experiences limited flight regime of say Mach 0 to Mach 2 or so, the RLV experiences a much wider range of flight regimes.

Hence the technology of an RLV is much more complex basically arising from the design of the control and guidance systems.

The ultimate objective of the RLV programme of ISRO is to enable the vehicle traverse a very wide range of flight regimes from Mach 0 to Mach 25 based on air-breathing propulsion for achieving two-stage-to-orbit (TSTO) launch capability.

The HEX series of experiments will be followed by the landing experiment (LEX), return flight experiment and scramjet propulsion experiment (SPEX).

The basic design of a scramjet has already been evolved.

The ghosts of Sykes-Picot

West Asia lies in tatters. Parts of the border between Iraq and Syria have been virtually erased by the Islamic State. Syria itself is divided among multiple groups. Iraq’s government has no control over at least a fourth of its territory.

Iraqi Kurdistan, an autonomous region, has demanded freedom from Baghdad. The Syrian Kurdistan region is being run by the Kurds themselves for the first time in several decades. The regional map is fractured in many more ways.

What triggered this crisis?

Part of the blame lies with a century-old agreement between Britain and France that is viewed as the source of the modern map of West Asia.

When the British and French signed the Sykes-Picot pact a century ago — on May 16, 1916 — to divide the huge land mass of the Ottoman Empire between themselves, their primary concern was to retain their colonial interests.

In the process, the map prepared by diplomats Mark Sykes and François Georges-Picot ignored local identities, leaving several ethnic and social contradictions unaddressed.

Even when actual boundaries were identified after the First World War, the focus was on colonial and regional interests, not on the political preferences of the people.

Against this background, it may not be a coincidence that over the years the most powerful political ideologies that emerged from the region directly or indirectly challenged the Sykes-Picot system.

Both Nasserism and Ba’athism sought to transcend the territorial nationalist boundaries. Egypt and Syria even went ahead to declare a United Arab Republic, an experiment that collapsed after the 1961 coup in Damascus. And now, even Abu Bakr al-Baghdadi, the leader of the IS, calls for an end to the “Sykes-Picot conspiracy”.

The modern map of the region may not bear any great resemblance to the original lines drawn by Sykes and Picot.

What matters more now than the actual Sykes-Picot map is the legacy of the agreement: foreign interventions. From the colonial carve-up to the Iraq war or the fight against the IS, foreign involvement in the region continues, and often exacerbates the crises rather than solving them.

Equally problematic has been the failure of West Asia’s leaders to live up to the challenges of their respective states. Over the years, they resisted reform and ran largely oppressive systems rooted in social conservatism and patronage. They showed no interest in tackling the problems the Sykes-Picot pact failed to address, such as the Kurdish question. Their authoritarianism simply sharpened the social contradictions in their states, while intra-regional rivalries made peace elusive.

The rise of the IS is a result of these external and internal problems. If the Iraq war unleashed sectarian and jihadist demons, they found a battlefield in Syria where President Bashar al-Assad’s dictatorship triggered a civil war, which was in turn worsened by his regional rivals. Both the interventionists from abroad and the warring dictators at home should rethink their approaches. Else, the ghosts of Sykes-Picot will continue to haunt West Asia.
